linseed oil and the drying qualities of which which the oil is extracted, as a forage 0F varieties of such seeds.

even exceed that of linseed oil. The object of this discovery is to provide a new product of manufacture forming a substitute for linseed oil, which new oil could be derived from its source at less expense and with a greater yield than it is possible to obtain oil from linseed.

A further object of the discovery is to utilize the residue left by the seed from cattle food.

The drying qualities of linseed oil are well known and it is the only drying oil which is of commercial importance and usually considerably adulterated with semidrying oils, diluents, etc., to reduce the price of the product. A number of substitutes have been placed on the market which contain as a part thereof the linseed oil, but

all those substitutes show objectionable properties and fail in their drying qualities, and do not answer the purpose for which the linseed oil can be used. I have discovered that a plant chia, belonging to the genus Salm'a and known as Salm'a kispam'ca of the Labz'atia; family yields a seed the oil of which has all the good properties of linseed oih even the odor. The 1 seeds of chia are used for the preparation of abevcrage which is sold publicly in the streets of Mexico. There are a number of v The chia plant is a shrub that reaches about 5 to 6 feet in height, the seeds are oval shaped, about 1 mm. in the longest diameter and about 1} mm. in the shortest diameter. The yield per hectar varies between 4,000 kg. to 1,000 kg. and in certain parts of the county two crops a year may beobtained.

It is remarkable that in all classic books on vegetable oils, such as, Lewkowitsch,

Application filed February 17, 1916. Serial No. 78,839.

' Chershefsky, Beilstein and Abderhalden, there is no mention whatever that oil can bederived from this species.

Experiments performed with seven varieties of seed gave the following results Average wt. of 1,000 seeds 1,166 gr., moisture average 7.33%. oil average in seed 32%. a

It will be remarked that the yield of oil from chia seeds exceeds the yleld of oil from linseed. The test of oil obtained from seeds coming from different parts of the country gave the following data:

The oil remains fluid at low temperatures;

similarly to linseed oil.

The residue left after the extraction of the close relation in drying qualities between this vegetable oil and that derived from linseed. The iodin value which is the index of the drying qualities of the oil is substantially that of'the best linseed oils.

While it is only possible to derive 29%" of oil from linseed it is possible to derive about 33% of -oil from seeds of chia, the

method of extraction being in no Way more difiicult than, that of linseed oil, the great yield of oil from. chia seeds, and the value of the residue reduce considerably the price of the finished product; In view of the fact that two crops a year may be obtained it is natural that the oil could be manufactured at a price considerably lower than the linseed oil.

I claim 1. As a new article of manufacture an oil derived from seeds of a plant of the Salm'a, family L'abiatiw. v

genus,

2. As a new article of manufacture an oil derived from seeds of Salm'a hz'spam'ca com-. monly known as chia.

3. As a new article of manufacture an oil derived from the seeds of the plant chia and having an iodin value of substantially 187.6.

4. As a new article of manufacture a vege- I table oil derived from seeds of the chia plant and characterized by an index of refraction nD 40 C. of substantially 1.4757, and an index of refraction ml) 17 .5 C. of substantially 1.48354.

5. As a new article of manufacture an oil derived from the seeds of the plant ehia and having a specific .9341, at substantially 15.5/l5.5.

gravity of substantially 6. As a new article of manufacture a vegetable oil having a specific gravity of substantially .9341, index of refgaction nD 40 0., substantially 1.4757, and 4117-17.? 0., substantially 1.48354, and it is characterized by iodin value of substantially 187.59, and Reichert-Meissl No. 0.1.

As a new article of manufacture a product from the process of obtaining oil from the ehia forming a cattle food.
